AUTOMOBILE TIRE Filed Nov. 25'. 1921 llrlatented thpii'i.. itd,

nu'rurtnnrrn in the county ot Kings and tate of New: 5 York,` have invented certain new and usetul`` l'n'iproven'rents` in` Automobile `flllires,` of which theiiollowing us a specification.

This invention relates to resilient tires 'for automobilcs andmorc partieularlyto an imjiiroved spring`` ti're especially` adapted tor use on antoinobilet' `rthe primary object of the inventioniiisto provide a spring tire which 'will include a plurality ot Springs arran;{i'edint`` ajinanner V which will give the desired resiliency to the wheel without the use off pneumatic tires.

Une of the objects of the invention is also to provide a resilient tire having laterally spaced and circumt'erentially spaced springs constructed in a manner which will absorb the shock occasioned by the wheel travelinp; over a roadway when the autornobile is in niotion.

ther objects of the invention will appear upon the consideration of the following detail description and accompanying draw-- ings, wherein:

lFig'ure 1 is a rag'mentary side elevation ot a portion of a tire constructed in accordance with my invention.

lligure 2 is a transverse cross section illustrating the graduating Springs entending laterally across the wheel riin.

Figure 3 is a longitudinal section through the clip element employed :tor connecting the spring elements together.

lFigure et is a cross section taken on the line 4-4: ot lFig. 1, and

Figure 5 is a fragmentary perspective view of? one of the spring elements.

liiteterringv to the drawing by numerals, the wheel rim 1 is preterably constructed ot' metal and is mounted upon the telly 1*' of the wheel supported by the spolies E2. 'Girciunferentially spaced around the circular rim i. is a plurality of retaining clips t which consist of complementary gripping members ti and t provided with openings to receive :tastening bolts 7 which are screw threadedly mounted in the rim 1. Itlhe side edges of the clip elements 5 and are beveled as indicated at 8 and 9 so that they may be properly litted together and the opposite end portions are constructed to receive the curved ends` 1D ot the semi-elliptical Springs ll. The

spring's ll are arranged in groups aroundithe rini as shown inFin's. 1 and 2 ot the drawn in the present instance, :tour leaves llbeing provided to constitute a single groiip ocspri-ng` element. The rigid clip member`-` 6 of the :tasteninn' structure is provided at opposite sides with curved recesses` which receive the Curved ends 1.0 when the Springs are j assembled together and`` these Curved ends are provided with openings 12 to receive pins 13 wherebiT the ends ot the spring's will he properly`` held inassociated relation. 'llhe movable clip members 5 are each provided at their endswith grippinglugs `14- which. are adapted to be lodired inthe ci'irved portions of the springs at the ends as indicated in 3 thus binding the Springs in position between the clips 5 and 6. A1'- ranged above and below the ends of the Springs vent rictional contact between the Springs and clip members. ln this .ma-nner the ends of the Springs are held to the rim of the 'wheel so that the intermediate portions ot the Springs will be in a position to otl'er the proper spring` when the wheel is in use.

its shown in Figure 2, the Springs are graduated transversely so that an arcuate tread surface is provided tor the tire at the point where the tire engages the ground, the 8 outermost Springs being considerably lower than the centermost Springs.

Additional tread members may be provided on the Springs it thought dcsirahla one ot these being illus'trated in Fig. i. at 15. This tread member is secured by the :lastening elements 216 to the outermost leaf ot the spring and its central portion is provided with fingers 17 overlapping the opposite sides of the leaves ot the spring' and adapted to engag'e lugs 18 on the lowermost leat ot the spring so that a r'igid hold is obtained by the tread member so that .it will act as a wearinp; plate at the point where the sprin member eng'an'es the ground surface. Ohviousljf other modiiications ot this tread member may be mounted upon the spring .it desired.

llt will be understood that additional spring' members and modiiications in the manner of constructing;` the device may bc employed upon different types oi Wheels as where the device is eiiiploved on heavy trucls and other Vehicles.

Minor changes may he made in the details are strips ot leather ll' which pre- 7 v ranged in groups for forming a plurality of spring members, the leaves in each group being adapted to be extended into the open ends of the said fa'stening members whereby they may be engaged by the said Cleats, the

Cleats having Curved recesses, the ends of the Springs being Curved to fit the recesses, one member of each Cleat being provided With lugs to engage the Curved portions of the said leaves Whereby they Will be rigidly held between the cleats.

2. A spring Wheel of the Character de- SCribed comprising in combination with a rim, a plurality of fastening cleats Comprising Complementary members adapted to be fastened together, the opposite ends of the cleats being opened, a plurality of leaves arranged in groups for forming a plurality of spring members, the leaves in each group being adapted to be extended into the open ends of the said fastening members whereby they may be engaged by the said Cleats, the cleats having Curved recesses, the ends of the Springs being Curved to fit the recesses, ono` member of each cleat being provided With lugs to engage the Curved portions of theI said leaves Whereby they Will be rigidly held between the cleats, the end of each loaf being provided with an opening, and pins extending through the openings whereby tlu` said leaves will be held in assembled relation.

In testimony Whereof, I have afiixed my signature in the Jresence of two witnesses.
